Vielklang VSTi/AU, a plugin instrument for instant audio harmonization, generates up to four voices from a single-voiced audio input. The progression of each individual voice is controlled by sophisticated harmony progression and voice leading models, resulting in musically meaningful harmonization without any configuration efforts.
With vielklang, you can thus easily generate and prototype natural sounding background vocals and brass sections, modify melodies and single-voice loops in terms of pitch and scale, and experiment with different harmonizations or chords triggered by different MIDI-inputs. It allows you to generate four voices, edit their harmonies and single pitches, and convert the audio to MIDI.
